LTC3109EGN#PBF Frequently Asked Questions (FAQ)

  • The maximum input voltage that the LTC3109 can handle is 38V, but it's recommended to keep it below 36V for reliable operation.

  • To optimize the inductor selection, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to choose an inductor with a saturation current of at least 1.5 times the maximum output current, and a DC resistance of less than 100mΩ.

  • The RUN pin is an active-high enable input that allows the user to turn the converter on and off. To use it, simply tie the RUN pin to VIN or a logic-level signal to enable the converter, or tie it to GND to disable it.

  • To configure the LTC3109 for a specific output voltage, use the FB pin and a resistive divider to set the output voltage. The FB pin is connected to the output voltage through a resistive divider, and the ratio of the resistors determines the output voltage.

  • The maximum output current that the LTC3109 can deliver is 2A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature.
